NEED FOR A NATIONAL SCHOLARS PROGRAM
WHAT IS THE NATURE
OF THE PROBLEM?
The scarcity of Blacks? Hispanics, and
American Indians in the doctoral scientific
and eng~neenng work force is unequivocal. In
1991 Blacks, Mexican Americans, Puerto
Ricans, and American Indians comprised 2.3
percent of doctoral scientists and engineers
(NRC 1994~. In 1987, an estimates! three
percent of full-time instructional staiT in the
natural science fields in college and
universities were Black or Hispanic (NCES
1993b). By contrast, it should be noted that
underparticipating minorities made up 22
percent of the total U.S. population in 1990
(NSF 1990, 4)
One consequence of the scarcity of
minority doctorates is the very low proportion
of such scientists among principal
investigators of research grants. In 1991 the
National Institutes of Health (NTH) awarded
5,217 new research project grants totaling
$~.! billion in funding. Twenty-five African
American researchers received grants,
representing 0.4 percent of the total awards
(NIH 1992~. Figures provided by the National
Science Foundation (NSF) indicate that in
1993 a total of 7,780 new competitive
research awards (excluding those made by the
Directorate for Education and Human
Resources) were made. Underparticipating
minorities received 287 or three percent of
total awards. Within that group there were ~ 5
American Indian, 89 Black, ~ 6 ~ Hispanic, and
22 Pacific Islander principal investigators.
Asians' who are not underrepresented among
doctoral scientists and engineers, received 728
grant awards.
The situation is unlikely to improve
markedly in the near filture if past trends are
any indication. In 1995 Blacks, Hispanics,
and American Indians earned 5.2 percent of
doctorates awarded to U. S. citizens and
permanent residents in the natural sciences
and engineering, compared to 2.2 percent in
1976 (see Table I). Over the past 10 years,
the number of doctorates awarded to
American Indians, Blacks, and Hispanics has
doubled, with their share increasing from 3.6
percent to 5.2 percent. By comparison, the
number of doctorates awarded to Asians
increased by almost 400 percent, with their
share increasing from 7.4 percent to 23.
percent.
OVERALL
EDUCATIONAL ATTAINMENT
While the dearth of minorities with
Ph.D.s is the most immediate and tangible
evidence of their underrepresentation in
science and engineering' their scarcity all
along the educational pipeline demonstrates
the need for a longitudinal approach to the

problem. Lack of educational attainment and
student choice narrow the pool of potential
minority scientists and engineers long before
graduate school. At the elementary and high
school levels, rapid growth in the Black?
Hispanic, and American Indian school-age
population has boosted total enrollment
numbers, obscuring the fact that enrollment
and persistence rates may not have risen and?
in some instances, have declined. Black,
Hispanic, and American Indian students are
lost from the educational system at far higher
rates than Asian and White students, with the
cumulative eject of these disparities
demonstrated by the severe under
representation of these groups among Ph.D.

recipients.
Ideally, an examination of the flow of minor-
ity students from high school to the Ph.D. would
follow the same cohort through its educational
journey, tracking individual completion and
attrition, and paying special attention to critical
transition points. Unfortunately, longitudinal data
on the same group of students covering this time
span do not exist. There are, however, data on
minority students at key points in their educational
careers which document the substantial narrowing
of the pipeline as students approach the doctorate.

African Americans
Indicators of progress are mixed. In
~ 99 I, 75 percent of Blacks between the ages
of IS and 24 had completed high school,
compared to 82 percent of Whites (U. S. Dept.
Of Commerce, Bureau of the Census 1993~.
For Blacks this reflects a gain of ~ 5
percentage points in high school completion
rates since 1970, narrowing, but not closing,
differences between Blacks and Whites on
this measure.
National test scores suggest that the
academic preparation of Black students has
improved markedly (Koretz 1992~. Since
1976 their combined verbal and mathematics
SAT scores increased 55 points, closing about
one-quarter of the total gap between White
and Black total mean scores (College
Entrance Examination Board 1993~. This is
especially significant since the proportion of
Black students taking the SAT doubled over
that time period.
Although the number of Blacks
enrolled in college has increased since 1976,
the rate of college attendance has not (NCES
1993b). Data from the Current Population
Survey show that in 1991, 42 percent of White
high school graduates, ages IS to 24, were
enrolled in college, compared to 32 percent of
Blacks (U.S. Dept. of Commerce, Bureau of
the Census 1993~. College graduation
continues to be a major hurdle. Blacks
received 6.7 percent of all bachelor's degrees
in 1980-~l, but their share fell to 6.2 percent
in 1990-91. Twenty-five percent of Whites,
ages 25 to 29, have completed four or more
years of college, compared to 12 percent of
Blacks.
Proportionately fewer Blacks pursue
graduate study relative to their representation
among college graduates. In 1991 Blacks
represented 5.4 percent of total graduate
enrollments (NCES 19931~.
Hispanics
The diversity of the Hispanic
population calls for caution in interpreting
aggregate statistics since the circumstances of
subgroups differ. Further, the immigration of
large numbers of Hispanics into the United
States makes it risky to generalize from
previous data to the future achievement of this
group. Between ~ 980 and ~ 990, the Hispanic
population grew by 53 percent, or about seven
times faster than the rest of the nation.
High school graduation presents a
continuing barrier to college participation for
Hispanic students, with only about one-half of
them completing high school. Compared to
Blacks, Hispanic SAT scores from 1980 to
1990 have shown little improvement. While
younger Hispanics have achieved gains on the
NAEP mathematics tests, the performance
level of 17-year-olds remains unchanged.
Hispanics made up 6.5 percent of
enrolled undergraduates, but they earned only
3.4 percent of bachelor's degrees awarded in
1991 (NCES 1993 c, 19936~. In graduate
education? Hispanics have recorded sizeable
gains, with enrollments jumping 74 percent
from ~ 980 to ~ 990. However, they still
represent only 3.0 percent of total graduate
students (NCES ~ 9936~.

American Indians
Although the native peoples of the
United States are usually classified as Native
Americans or American Indians and include
Alaskan natives, there are actually over 400
different nations or tribes. This diversity is
not usually recognized. There are an
estimated I.9 million American Indians,
representing about 0.8 percent of the U.S.
population (O'Brien ~ 992~. Over one-third of
American Indians fad! to complete high
school. While the number of American
Indians enrolled in college has increased in
the past decade, no gain in the proportion of
American Indians in higher education has
occurred. In ~ 99 ~ about 4, 500 American
Indians earned bachelor's degrees (NCES
1993c); ofthat number, only 70 degrees were
awarded in the physical sciences (NCES
19936~.

SCIENCE, MATHEMATICS, AND
ENGINEERING EDUCATION
Disparities in participation and
academic achievement in science between
minority and non-minor~ty students become
increasingly pronounced from high school
through doctoral training. Many students
enter college with an interest in science but
switch from science before graduation. Astin
and Astin ~ ~ 992) studied factors in the
backgrounds and educational experiences of
college students that affected their study of
science and entrance into scientific careers.
They found that close to 29 percent of college
freshmen began college planning to major in
science or engineering, but only 17 percent
ended up with degrees in these fields' a
decline of 40 percent. While it is normal to
expect that many undergraduates will change
their choice of majors during college,
minority students (with the exception of
Asians) were more likely to leave science than
White students' as shown in Table 2.
Even as students move into doctoral
study, they continue to switch out of science.
According to the NRC Survey of Earned
Doctorates, of the 1992 Black Ph.D.s with
bachelor's degrees in the physical sciences,
less than one-half received the Ph.D. in one of
those fields. Thirteen percent shined to the
biomedical sciences, while 23 percent earned
a doctorate in education. Among nonminority
White students, field shifts were much less
pronounced. Seventy percent remained in the
physical sciences, while ~ ~ percent shiDed to
the biomedical fields, and only 5 percent
moved to education. This pattern has changed
little in the past 20 years (NBGE 19764.
BARRIERS TO PARTICIPATION
Peng' Wright, and Hill (1994) found
that African American, Hispanic, and Native
American children generally have lower
achievement scores and have completed fewer
advanced science and mathematics courses by
the time they graduate from high school than
have Asian American or White students.
They concluded that "without additional
assistance these students would be
nano~cappeo In taking rigorous science and
mathematics classes at the college level; it is
much harder for them to be scientists and
engineers." In 1994 the College Entrance
Examination Board reported that among high
school seniors who took the SAT tests, ~ ~
percent of Blacks had completed calculus,
compared to 22 percent of Whites and 40
percent of Asians. For college students, Astin
and Astin (1992) found that the "strongest and
most consistent predictor of changes in
students' interest in science majors or careers

is the student's entering level of mathematical
and academic competency."
In a study of how opportunities to
learn science and mathematics are distributed
within the educational system, Oakes (1990)
concluded that the divergence of Black and
Hispanic students from the science pipeline
occurs as early as elementary school, when
these students are more likely to be placed in
low-ability classes and are less likely to
participate in accelerated or enrichment
programs. Stewart (1993) observed that the
practice of grouping students by presumed
levels of ability has a pernicious effect:
"Achievement in children is so flexible and
responsive to the environment that
expectations become prophecy. Students
treated as losers, act like losers; students
treated as gifted and talented, act like gifted
and talented." And Cantu (1994) argues that
minority children will lose out on access to
educational excellence if less is expected of
them than of other children.
There are also factors that are a
consequence of lower economic circum-
stances and social class, and while they affect
all students in these situations' there is a
· · · . .
c ~sproport~onate Impact on minority stuc ents
because of the close correlation in our society
between race/ethnicity and socioeconomic
status (SES). The data shown in Table 3
demonstrate that minority students are
overrepresented among those in the lowest
socioeconomic group. Among 1990 high
school sophomores, approximately 40 to 50
percent of Hispanic, Black, and American
l:ndian students were in the low SES category'
compared to less than 20 percent of the Asians
and Whites.
Low persistence in higher education is
not confined to poor or otherwise
disadvantaged minorities. Even students from
middle class minority families are likely to be
"at risk" in higher education. Among students
from more advantaged backgrounds, there are
sizable differences between the college

graduation rates of Black and Hispanic
students and those of White and Asian
students. Seven percent of White, ~ percent
of Black and 5 percent of Hispanic 1980 high
school seniors from the lowest SES quartile
had completed a bachelor's degree by 1986,
while 40 percent of 1980 White high school
seniors from the highest SES quartile earned
a bachelor's degree or higher by ~ 986,
compared to 26 percent of Black and IS
percent of Hispanic students (NCES 1993b).
The evidence presented above
suggests that although differences in
educational achievement between under-
represented minorities and Whites narrow
when income or other indicators of SES are
considered, they do not disappear. Factors
associated with minority status appear to be
an added clisadvantage with respect to
educational achievement.
INSTITUTIONAL CLIMATE
Why, it is asked, do some institutions
and academic departments have a strong
record of accomplishment in producing
minority graduates while others do not?
Minority institutions have excelled in this
regard and continue to produce a large share
of Black college graduates. Historically Black
colleges and universities (HBCUs) have been
particularly successful in producing science
graduates. In 1993 they awarded 48 percent
of bachelor's degrees earned by Blacks in
computer science and mathematics, 47 percent
in the physical sciences, and 42 percent in the
life sciences (NSF 1995,
82). Xavier
University, one historically Black college, is
especially notable in this regard; almost one-
half of its students graduate with degrees in
mathematics and science (TOM 1994~.

Figures reported by the National
Action Council for Minorities in Engineering
(NACME), however, indicate that 39 percent
of minority freshmen engineering students
nationally complete their undergraduate
degrees, compared with about two-thirds of
nonminority students. This graduation rate
has remained virtually unchanged over the
past 10 years (Morrison, Griffin? and
Marcotullio 1995~.
Data from the American Institute of
Physics (AlP) indicate that few under-
participating minorities have earned Ph.D.s in
physics, and that only a small number of
institutions have produced those doctorates.
Ten universities accounted for one-half of all
Black U.S. citizens earning Ph.D.s in physics
from ~ 973 to ~ 99 ~ . Stanford University
graduated 19 Black Ph.D.s over the 19-year
period, or an average of one per year. One
hundred thirteen physics departments did not
award a single Ph.D. to Black students.
WHY IS THE
PROBLEM IMPORTANT?
The urgency of this issue is more than
a matter of individual equity. Our greatness
as a nation will increasingly depend on the
capabilities of our scientific en c} technological
work force. The national interest is best
served by assuring that doctoral scientists and
engineerings are drawn from among those
individuals with the greatest intellectual
promise. Although talent is widely distributed
throughout all population groups, the abilities
of some groups in our society have been
underdeveloped. If we fad] to identify and
cultivate their potential, the excellence of our
human resources at the highest levels of
science ant! engineering will be less than what
it can and should be.
Demographic trends are compelling.
By the year 2030, minorities will comprise
more than one-half of the nation's children.
As we move into the next century, not only
the economic vitality but the fundamental
social stability of the nation will depend on
our ability to educate minority youth. If
American education fails here, the
consequences for our society will be
profound.
WHY IS A NATIONAL
SCHOLARS PROGRAM NEEDED?
Concerted national action is essential
if we are to expand the pool of minorities with
the appropriate qualifications to become
faculty in colleges and universities or to
obtain other high-level positions in the
science and engineering work force. Two
decades of efforts have produced only
. . . . . . .
c lsappo1ntlng progress in increasing the
number of minorities earning a Ph.D. in
science and engineering. It is reasonable to
ask: Why is a National Scholars Program
likely to make a contribution to solving this
problem when many other initiatives
apparently have had only modest success?
In 1992 AAAS issued a report on the
status of minorities in science and
engineering. Drawn from dozens of
interviews with government officials,
educators, and industry personnel, the report
highlighted several reasons for the lack of
progress in increasing the number of
minorities earning a Ph.D., including poor
program oversight; little commitment from
faculty; vague or unrealistic goals; inadequate
or erratic funding; emphasis on recruitment
and not retention; a focus on higher education
that ignored problems at the precollege level;
and lack of tracking of student progress.
Although there may appear to be a large

number of programs, the report pointed out
that too many have operated in isolation, thus
failing to develop the infrastructure necessary
to sustain momentum in their efforts.
Despite this general disappointment,
there are many exemplary intervention
programs. The Mathematics, Engineering,
and Science Achievement (MESA) program,
for example, was founded in ~ 970 "to increase
the number of historically underrepresented
students who graduate from four-year
· e e ~ ~ e e e
universities wit ~ a degree In engineering,
computer science, or other math-based fields."
From this and other pioneering efforts has
emerged a substantial base of knowledge
about what does work. These proven
strategies have provided critical information
that can be used in developing a compre-
hensive, systematic approach to increase the
number of minorities succeeding in science
e
ant engineering.
Ultimately, genuine reform should and
must obviate the need for targeted programs.
The existence of add-on or set-aside programs
may have the unintended but serious eject of
limiting or directing minorities to those
designated programs, rather than including
them in the much larger pool of mainstream
resources and opportunities. However, reform
will not be accomplished immediately, and
until such fundamental change is realized,
carefully designed targeted programs such as
the National Scholars Program will serve two
necessary purposes: first, to facilitate the
success of current minority high school and
college students, and second, to act as a
catalyst for lasting change.
